Leverage advanced integrated analog and software implementations to provide flexibility across a wide range of design requirements

As the rollout of smart meters continues around the globe, smart grid and smart metering developers need a scalable portfolio of metrology SoCs with a wide array of memory, low-power and security options. Texas Instruments has expanded its

portfolio of three-phase smart e-meter SoCs with a number of additional features such as advanced integrated analog and software implementations to provide flexibility across a wide range of design requirements.

The integrated on-chip flash memory allows developers to include communication stacks for both wired and wireless protocols such as ZigBee®, wM-Bus, power line communication (PRIME, G3-PLC, IEEE-P1901.2) and RF mesh networks, which enables the meter to become an extension of smart homes and the IoT.

The SoCs include high-performance delta-sigma analog-to-digital converters (ADCs) for energy measurement products which require high accuracy across a wide dynamic range and include advanced security and electrostatic discharge (ESD) features. A 128-bit Advanced Encryption Standard (AES) hardware-accelerated module speeds encryption time, improves meter security and performance. With more flash memory integrated on-chip, smart grid developers can incorporate more sophisticated metering features like multi-dwelling dynamic pricing, large buffers for interval data, DLMS/COSEM for meter data formatting, and communication stacks for both wired and wireless protocols.
